I have always eaten Iams --as a kitten I would not eat Purina Kitten Chow and my vet suggested Iams and I loved it. Anyway, my mommy was at the grocery store the other day and they were giving out free 4 lb bags of the new Purina Naturals for cats. She brought it to my nana to feed her newly acquired adult cat (who also happens to be orange--his name is Elvis and i don\'t really like him--i have to remind him constantly that i am in charge) and he appeared to like it. Is there is one that is better than the other? My mommy wants to know if she should switch my food or let me continue eating Iams.
